CVE-2026-44636: CWE-122: Heap-based Buffer Overflow in saitoha libsixelCVE-2026-44636 0 libsixel versions from 1. 4. 4 up to but not including 1. 8. 7-r2 contain a heap-based buffer overflow vulnerability due to a signed integer overflow in allocation size calculation within the sixel_encode_highcolor function. The vulnerability arises because width and height parameters are only validated to be greater than zero, without an upper bound, allowing a multiplication that can overflow and cause an undersized heap allocation. This leads to out-of-bounds writes during encoding. The issue is fixed in version 1. 8. 7-r2. Join the discussion | CVE Database V5 | 05/14/2026, 20:01:27 UTC Added: 05/14/2026, 20:06:48 UTC |
